Abstract: METHOD AND APPARATUS FOR DISTRIBUTING CONTROL        SIGNALS                           Abstract A method and apparatus are described in which the control signals for a data channel are transmitted along with the channel address.  The control signal and its address are transmitted on a bit interleaved basis in response to CONTROL select signals that are generated as part of the frame.  The CONTROL select signals are distri-buted relatively uniformly throughout the frame.  At the receiver, the bits of the control signal and its address are reassembled and the address is used to route the control signal to its proper channel.  Further, the bandwidth assigned to control signaling is increased by inserting CONTROL select signals in all time slots that are available in the frame after the necessary channel select signals and other overhead select signals have been assigned.  This technique is particularly advantageous in a system having a fixed aggregate transmission bandwidth, variable loads and the capability of automatically reconfiguring the frame.

Abstract: Abstract of the Disclosure The toy electric oven comprises a housing having a chamber therein.  In the lower portion of the chamber there is an upstanding socket that contains therein a 60 watt chandelier bulb.  The sides of the bulb are surrounded by a parabolic reflector that reflects heat upwardly from the bulb into the upper portion of the chamber.  A rack is located in the upper portion of the chamber, the rack having a lower plate with  an opening therein so that heat can impinge upon the underside of a utensil when placed in said rack.  The rack also has an upper plate provided with an opening.  The opening in the upper plate is immediately beneath a window in the top of the housing so that the child can view whatever is being heated when supported on the rack.  A slide switch is employed to supply power to the chandelier lamp.  The operating button of the slide switch is actuated between its open and closed positions by means of a switch plate having an arcuate slot therein possessing a sufficient amount of eccentricity so that the operating button of the switch is moved from its open position to its closed position when said switch plate is rotated in one direction by a manually-operated knob.  The switch plate includes a guard portion that is moved into obstructive relation with the entrance leading to the rack when the switch is closed.  A gate is also moved into obstructive relation with the entrance by means of two bimetallic arms that when subjected to sufficient heat flex so as to shift the gate from an open or raised position to a closed and blocking position relative to the entrance.  Should the temperature within the oven reach an excessively high level for a certain  time period, then a thermal switch opens to completely interrupt the power being supplied to the lamp socket and the chandelier bulb mounted thereon.

Abstract: Abstract of the Disclosure An automatic picture coding system including a method for converting a bit-map image of the picture to vectors as the picture is being scanned. The bit map is delayed as it is being generated to form a series of tessellations or windows of data. The windows are propagated through a series of neighborhood-logic elements which perform data transformation operations such as growing, smoothing and thinning of the bit-map image. A bit stream output from the neighborhood logic which output includes only line and edge features of the original picture is transferred serially to a microcomputer where the features are parti-tioned into a plurality of line segments. Each line segment is chain coded and temporarily stored, as it is acquired, in a corresponding one of a plurality of lists, the lists being linked in an order corresponding with the order in which the segments are acquired. When the storage of each chain-coded segment is completed, the segment is converted to vectors and transmitted to a user device for display, storage, or further processing, the lists in which the converted segments were stored being unlinked and deallo-cated. The process is continued until the entire document has been scanned and converted to vectorial data.

The conduits to be interconnected are attached to a hollow stationary body, or stator assembly, which is comprised of three sections, or elements, each of which is cylindrical in exterior form. There are fluid flow paths in a rotating body, or rotor assembly, which is located inside the stator assembly. The rotor assembly assumes various positions according to the cycle steps and distributes fluid flowing into and out of the valve in a different manner in each cycle step. There are spaces between the rotor and stator assemblies which contain sealing means for prevention of leakage and definition of flow passages. In one embodiment, the rotor assembly is configured such that axial forces exerted by the fluid streams are exerted equally in both directions, thereby providing a balanced rotor assembly floating between its axial restraints.

Abstract: PROCESS FOR THE PREPARATION OF COMPLEXES OF ONE MOL OF DIMERIZED OR LOW-OLIGODIMERIZED 4,4'-DIISOCYANATO-DIPHENYLMETHANE AND TWO TO THREE MOL OF 4,4'-DIISO-CYANATODIPHENYLMETHANE, CORRESPONDING COMPLEXES, AND        THEIR USE FOR POLYURETHANE PRODUCTION      ABSTRACT OF THE DISCLOSURE The present invention relates to a process for the dimerization of 4,4'-diisocyanatodiphenylmethane from emulsion in apolar solvents with the formation of complexes and to the complexes obtainable for the first time by this process.  The complexes consist of one mol of low molecular weight 4,4'-diisocyanato-diphenyl-methane-uretdione or its low oligomers corresponding to the idealized formula (I)   (I) (n = 0 to 0.5, where n is the average degree of oligo-merization of the dimer) and 2 to 3 mol of 4,4'-diisocyanatodiphenylmethane (MDI)                  (II).        In the process according to the invention, 4,4'-diisocyanatodiphenylmethane (II) in the molten form is emulsified in apolar solvents.  Dimerization is started in the presence of conventional dimerization catalysts at temperatures above the melting point of MDI, preferably up to an upper temperature limit of 50 to 60°C.  The temperature is then lowered to <40°C.  If desired, dimerization can be stopped when an isocyanate content of from 22.4 to 26.9% has been reached.  The product is then worked up at low temperatures, preferably at 0 to 25°C.  The complex obtained is claimed as a new substance.  The use of the complex for the production of polyurethanes is also claimed.
